FRTSCE, OF HAMILTON, OHIO, ASSIGNOR TO THE EAG-LE WOODENWARE MANUFACT'URNG COIVPNY, 0F HAMLTON, OI-O, A CORPORATION OF OHIO MOP VVRINGING 'UNT Application filed May 24, 1930.

rlhis invention relates to improvements in a portable mop wringing unit.

An object of the invention is to provide a novel device of the above character comprising a portable frame Vsupporting a mop wringer mechanism and having a platform for supporting a removable bucket beneath the wringer mechanism.

Another object is to arrange the manually operative elements of a device of the above character so as to render the device facile of operation.

Another object is to provide a device for the purpose stated which will permit use of l5 a much larger bucket than could ordinarily be employed in mopping or cleaning jobs.

Another object is to provide a novel means for holding the device against movement along a floor during the wringing operation.

These and other objects attained by the means described herein and disclosed in the accompanying` drawings, in which:

Fig. 1 is a perspective view showing the device in the inoperative or mop receiving condition.

Fig. 2 is a cross-sectional view takeuon line 2 2 of Fig. 1 showing the device in the operative or wringing position.

Fig. 3 is a side elevational view taken on line 3 3 of Fig. 1.

The device of this invention comprises a mop wringer mechanism, indicated generally by 5, superposed upon a frame 6 tractionally supported upon casters or wheels 7, and having associated therewith a platform or container support 8. The platform is located directly beneath the wringer mechanism and is adapted to support a bucket or other container indicated by broken lines 9. Liquid squeezed from a mop 10, therefore, will be received by the bucket. T he arrangement of wringer, platform and tractional frame makes possible the use of a large container or bucket of liquid for cleaning purposes. and at the same time facilitates handling of the bucket and operation of the wringer mechanism.

The legs of the frame are indicated at 12, and each leg is provided with a wheel or caster 7. The legs preferably are of angle tional movement.

iron and are held in position by the platform L8 and auxiliary frame 13 to which they are secured. The platform and frame 13 may be of any desired shape, though they are represented herein as rectangular. The auXiliary frame 13 comprises the joined memibers 14, which may be of angle iron stock. A pair of opposed members 14: has secured thereto the spaced parallel wringer support members 15 each of which may be of angle iron stock, one leg 16 of each being disposed in a vertical plane. To each leg 16 is secured a track member 17 of the wringer mechanism.

The track members provide a support for` the rotatable idler rolls 18, thev cooperative manually rotatable roll 19, and the pressure mechanism which is actuated by means of a lever or the like 20vfor advancing and retracting the roll 19 relative to the idler rolls. The rolls 18 each have an axle lshaft 21 the opposite ends of which are journaled in bearings in the track members, for rota- The tracks formed by the slots 22 are adapted to receive the live aXle shaft 23 upon which the roll 19 and crank 24 are fixed, and it will be noted that the slots are so arranged, relative to the idler rolls, that advancement of the drive or crank operated roll will dispose said roll partly between the idler rolls. Thisposition is illustrated in Fig. 2. It willbe readily apparent that operating the crank 24 when the rolls are in the operative position shown in Fig. 2, will serve to squeeze and remove liquid from the mop.

The means for advancing and retract-ing the drive roll may consist of a pair of spaced parallel arms 25 movable to advanced and retracted positions by means of links or the like 26 which are iXedly mounted upon the shaft 27 to which thelever 2O is keyed, or otherwise iixed. One end of each arm 25V is pivoted, as at 28, to a free end of each link. Upon moving the lever 2O downwardly, the arms 25 and roll 19 will be advanced toward the idler rolls. The shaft 23 of roll 19 may be journaled in the arms 25, or it may have a yielding connection therewith as indicated in the drawings.

Any suitable yielding connections may be provided between the arms 25 and the rotatable shaft 23 of roll 19. In the drawings is shown a yielding connection comprising a stem or reciprocating member 30 having on one end thereof a bearing block 3l for rotatably receiving the shaft 23, and on the opposite end a screw thread 32 for cooperation with an adjusting nut 33. The arm 25 is provided with fixed spaced abutments 34 and 35 each having a. perforation for receiving the stem 30. A compression spring 36 and the nut 33 encircle the stem .30 and are disposed between the abutments. From the foregoing, it will be readily apparent that the stem may be moved outwardly against the resistance of the spring, and that the nut may be adjusted along` the stem to vary the spring tension. Then the mop 10 (Fig. 2) is squeezed between the drive and idler rolls, the spring may yield, as indicated in Fig. 2, and the amount of liquid to be squeezed from the mop may be regulated by adjusting the nut. The yielding connection is the same for both arms 25.

As indicated in Fig. 2, the pivotal points 23. 27 and 28 are so located that their axes may, upon increment of lever 20, be disposed in a common plane, and upon further movement of the lever the axis of pivot 28 may be moved off-center or past center to render the spring effective for precluding return of lever 20 to the inoperative position. With the parts in the past center relationship, the links 26 may abutthe frame as at 37, thereby limiting rotation of shaft 27 under the iniuence of the compression spring.

Two of the legs 12. preferably those adjacent to the links 26. may have secured thereto a foot piece 38 upon which an operator may stand while operating the wringer mechanism. the purpose thereof being to preclude shift-ing or rolling of the device along the floor. The footpiece may be provided with pcrforate ends 39 screwed or otherwise secured to the legs (Fig. 3), the intermediate portion 40 of the foot piece being but slightly spaced from the floor. The foot piece may be sufliciently resilient to Contact the floor when the foot is placed thereon, or it may be nonresilient and so spaced from the floor as to contact the a ch of the operators shoe. thereby serving as a stabilizer for the tractional frame during the wringing operation.

From the foregoing it should be readily apparent that the device is simple of operation and construction, and that much effort on the part of the user is saved due to the ability of the device to accommodate large sized containers which need not be emptied and refilled as often as smaller containers. In asmuch as the. wringing operation imposes no strain on the container when used in conjunction with the device of this invention, the life of the container is considerably extended.

It is to be understood that various modifications and changes in structural details of the device may be made, within the scope of the claims, without departing from the spirit of the invention.

What is claimed is:

l. ln combination a tractional frame comprising legs, a platform for a container supported by the frame, a wringing device supported by the frame above the platform and comprising a crank shaft for actuating the wringing device from an operators position in front of the frame, a slightly elevated foot piece connecting adjacentlegs and extending across the front of the frame in parallelism with the crank shaft for use simultaneously with the wringing device and an elevated hand lever arranged for shifting the crank shaft and disposed outwardly of and beyond the frame at hip level when the device is in the operative wringing position, whereby an operator may stabilize the device by leaning against the extending hand lever while depressing the foot piece and operating` the crank shaft.

2. In combination a tractional frame coinprising legs, a platform for a container supported by the frame, a wringing device supported by the frame above the platform and comprising a crank shaft for actuating the wringing device from an operators position in front of the frame, a foot piece connected adjacent legs and extending across the front of the frame in parallelism with the crank shaft for use simultaneously with the wringing device, and an elevated hand lever arranged for shifting the crank shaft and disposed outwardly of and beyond the frame at hip level when the device is in the operative wringing position, whereby an operator may stabilize the device by leaning against the extending hand lever while depressing the foot piece and operating the crank shaft.

In testimony whereof, l have hereunto subscribed my name this 6th day of May, 1930.
